Specifying pedestrian guard rail

2m panels, 900mm high, 50 x 30mm RHS frame with 12mm bars at 110mm centres, galvanised to BS EN ISO 1461. What to decide before you order.

Reviewed by AA Fencing Technical Team, Technical Sales, AA Fencing UK · Updated 4 August 2026

Pedestrian guard rail does the opposite job to crash barrier. Crash barrier keeps vehicles out of the pedestrian space; guard rail keeps people out of the traffic space — the low railings at crossings, school gates, bus stops and busy junctions that stop somebody stepping off the kerb where they should not.

Ours are designed and manufactured in house, in two styles, PG1 and PG2.

12mm bars at 110mm centres leaves just under 100mm clear between bars. Panels are 2m, so a run is set out in whole panels and the odd length gets made to suit rather than cut on site.

The letterbox option

The upper 'letterbox' gap is a horizontal opening near the top of the panel. It exists so drivers can see a child standing behind the railing at a crossing, and so pedestrians waiting can see approaching traffic through it. On a crossing approach it is usually worth having; on a plain length of footway railing away from a junction it is not.

Fixing

Panels go in dig in or bolt down. Dig in for a new footway or verge where you can break ground; bolt down where the panel is landing on an existing slab or a finished pavement that nobody wants dug up. Bolt down puts the load into the anchor fixings, so the same caution applies as anywhere else — the concrete has to be sound at each fixing point.

What to tell us before you order

  • The run length, and whether it turns any corners.
  • PG1 or PG2 — and if you are not sure, tell us what the scheme drawing says and we will match it.
  • Whether you want the letterbox gap.
  • Dig in or bolt down.
  • Galvanised only, or galvanised and powder coated to a RAL colour.

Frequently asked questions

How big are pedestrian guard rail panels?

2000mm long and 900mm high, built from a 50 x 30mm RHS frame with 12mm round bar infill at 110mm centres, hot dip galvanised to BS EN ISO 1461.

What is the letterbox gap on pedestrian guard rail?

A horizontal opening near the top of the panel that improves sightlines at crossings — drivers can see a child standing behind the rail, and people waiting can see traffic through it.

What is the difference between PG1 and PG2?

They are our two guard rail styles on the same frame and panel size. If a scheme drawing names one, quote it to us and we will match it; if you are specifying from scratch, tell us the location and we will advise.
